You can "learn" to like only top-end gruppos, but there's nothing wrong at all with intro-level gruppos. I've got a Sora triple bike and a DA Cervelo, and the Sora is excellent - I don't miss my DA much when I'm on my Sora. It does need a bit more adjusting after a few months of cable stretch, but I suspect that's more of the triple vs double issue vs the Sora vs DA issue.
